Solution Overview

Problem

Existing sealing devices for wall penetrations face challenges in versatility, as they often require multiple devices for different line diameters and struggle with reliable sealing under varying conditions, including water pressure and humidity, due to material stiffness or softness limitations.

Innovation Solution

A modular sealing device with reversibly detachable sealing cones of varying diameters that can be connected to a single sealing body, allowing for easy adaptation to different line sizes and enabling manual assembly and disassembly without tools, using a plug-in connection system that allows for elastic deformation to generate sealing force.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a relatively stiff material is used for the sealing body to apply high sealing forces, then reliable sealing under water pressure is achieved, but manual assembly and disassembly becomes impossible requiring clamping devices

Engineering Contradiction:
Improvesealing reliability under water pressureVSAvoidmanual assembly and disassembly
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The sealing device is divided into a sealing body and separate sealing cones that can be independently assembled and disassembled. The sealing cones are inserted into the sealing body through a reversibly detachable connection, allowing the sealing cones to be removed and replaced without removing the entire sealing body from the wall opening.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sealing cones are nested within the sealing body, with each sealing cone having a conical sealing section that fits into the sealing body's internal structure. The sealing cones can be inserted and removed from the sealing body while the sealing body remains installed in the wall opening.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If a relatively soft material is used for the sealing body to enable manual assembly and disassembly, then ease of operation is improved, but sufficiently high sealing forces cannot be applied compromising sealing reliability

Engineering Contradiction:
Improvemanual assembly and disassemblyVSAvoidsealing reliability under water pressure
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The sealing cones are pre-assembled onto the lines before insertion into the sealing body. The conical sealing sections are designed to be inserted into the sealing body in a specific sequence, with each sealing cone being firmly held in position by the overlapping arrangement and reversibly detachable connection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The conical sealing sections have a curved conical shape that allows them to be inserted into the sealing body and generate sealing force through their geometric form. The conical geometry enables the sealing surfaces to contact and seal against the wall opening and lines effectively.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Adaptability or versatility

If multiple different sealing devices are kept available for different line diameters, then adaptability to various line sizes is achieved, but device complexity and inventory requirements increase

Engineering Contradiction:
Improveaccommodation of different line diametersVSAvoidnumber of different sealing devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single sealing body is designed to accommodate multiple different line diameters by accepting different sealing cones. The sealing body has a universal structure with an internal cavity that can hold sealing cones of various sizes, allowing one sealing body to serve multiple functions for different line configurations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The sealing device allows dynamic reconfiguration by enabling the removal and replacement of sealing cones. The reversibly detachable connection permits the sealing cones to be exchanged based on the specific line diameter requirements, transforming a static single-purpose device into a dynamic multi-purpose system.

Inventive Principle:
Principle #15Dynamics
